Abstract

A total of 321 observations of the Delta Scuti star BD −6°4932, obtained in 1968 by Hall and Mallama (1970), are analyzed. We find four frequencies which represent the light curves satisfactorily.

The three periods:P 1=0 d. 240,P 3=0 d. 182 andP 4=0 d. 114 seem to correspond to the radial modes of pulsation withK=0, 1, and 3, respectively. The last periodP 2=0 d. 220 can be related to a non-radial mode.
